or SATA, is a
new hard drive interface that effectively improves data transfer rate of
hard disk. Just like such differential signaling systems as differential
SCSI, USB and firewire devices, serial ATA data cable set consists of one pair for differential transmission of data to the device, and one pair for differential receiving from the device.
This type of hard drive interface requires that data be transmitted serially.
Most popular brands of SATA 2 & SATA 3 hard disk drives include Western Digital and Seagate.
